Our performance cylinder bolt kit is designed for R56 N12, N14, N16, N18 OEM replacement and street performance engines that require more strength and durability than stock bolts. The bolts are made from high-quality steel and are heat-treated to withstand high temperatures and stress. They are also corrosion-resistant, so they can withstand engine coolant exposure.
This kit includes all the necessary bolts for a complete cylinder head installation, including head bolts and washers.
Great for street and mild performance engine builds.
